There is new speculation that all might not be well between chart topper Ciara and the father of her newborn baby, rapper Future. The new celebrity mother stepped out for the first time since giving birth to her son Future, Jr. last month without her boyfriend.

Wearing an all-black ensemble, Ciara showed off her amazing post-baby figure as she strolled with her newborn son and a few close friends outside her neighborhood in Los Angeles, Calif. over the weekend.

Rumor has it that Ciara is trying to cope with rumors that the Atlanta rapper has been cheating on her with Rihanna, as the two have become close while recording a new album together. A source told MediaTakeOut.com that Future and Rihanna "couldn't keep their hands off each other" as they openly flirted with each other in a recording studio.

"There was a lot of tension in the air, like [Future] and [Rihanna] wanted everyone to leave," the source said. "And they kept looking at each other and laughing - there was definitely something going on between them."

Rihanna has not commented on the speculation, although Ciara did hint on her Twitter account that there might be trouble behind closed doors as she tweeted, "#PrayingisPowerful."

Ciara gave birth on May 19 to Future Jr., who weighed in at 9 lbs. 10 oz. This is the first child for the singer and the second for Future, who already has an 11-year-old son with former girlfriend and model Jessica Smith.
